C9 Christmas Light Strings and Spools for custom commercial and
residential lighting. Screw C9 bulbs into standard E17 sockets and
display fun Christmas light themes. Retrofit LED bulbs and incandescent
bulbs with E17 bases are designed to screw in and out of sockets for
seasonal lighting and full customization. Add zip plugs to create custom
lengths, calculate wattage to shop by amp capacity, and choose from
spacing options ranging from close 6" spacing to 15" or even 18" spacing
for outlining large buildings with lights. C9 light strings are designed
to work with any E17 base bulb.
What are stringers and spools?
Stringers and spools come ready to use in pre-cut lengths for any
decorating project. Available from 25' stringers to 1000' spools with a
variety of bulb spacing, custom decorating projects are made easy with
C7 stringers. C7 stringers and spools have empty E12 Candelabra bases,
ready for any incandescent or LED C7 bulbs. Sockets feature weep holes
for water drainage.
How can I customize my spools?
Splicing, or cutting stringers and spools, is the best way to decorate
custom projects. To splice the wire to a custom length, measure the
wire, cut it at the predetermined location, and place a zip plug on the
end, creating a female or male plug for outlets or end-to-end runs. Any
color or style bulbs from incandescent to LED can be chosen for these
spools, so decorating for themes, whether for sports teams, breast
cancer awareness, or weddings, becomes easy.
What is the difference between SPT1 and SPT2?
Light stringers and spools are available in SPT1 and SPT2 wire, which is
the insulation covering the copper wires within the cord. SPT rating
refers to the thickness of the wire itself, and how much current it can
safely contain. Typically SPT1 wire is rated for 7 amp, and SPT2 is
rated for 10 amp. C9 incandescent bulbs are typically powered using SPT2
wire. C9 LED bulbs can often use SPT1 wire due to the reduced power draw
in LED technology. When connecting wire end-to-end and using zip plugs
for custom lengths, SPT rating needs to remain consistent.
